class VocabularySerializationTest in Drupal 10

Regression test for https://www.drupal.org/node/2807263.

When a Vocabulary entity is unserialized before the modules have been loaded (which happens in the KernelPreHandle Stack middleware), then the constants that the Vocabulary entity uses are not yet available because they are set in taxonomy.module. This means that for example the PageCache middleware cannot load any cached Vocabulary entity, because unserialization will fail.
